IMPROVEMENT IN KNITTING-MACHINES.

The Schedule referred to in these Letters Patent: and making part of thesame.

To all whom it may concern Be it known that we, G. \V. Fours, of Boston,in the county of Suffolk and State of Massachusetts, and JAMES L.BnAXsoN, of Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Knitting Machines; and we dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanying drawingwith letters marked thereon making apart of this specification, inwhich- Figure 1 represents one-halt of the inner periphcry of therotating cylinder used in Bickfords patent, dated September 10, 1868,and also shows a part of our device.

Figure 2, a vertical section of one-half of the machine, representing aneedle as it is when in use.

Figure 3, the same section, representing 'thcncedle as it is droppeddown into one ot'the vertical grooves in the stationary cylinder.

Figure 4, a perspective view of the spring device which closes the upperend of the vertical groove,

and prevents the needle from falling out of the camgroove.

The nature of our invention consists in a particular construction andarrangement of devices, as will be hereinafter fully described, wherebyany of the needles upon which it is desired not to operate may belowered out of operation.

To enable others to fully comprehend the construction and operation ofour invention, we have marked like parts with like letters, and will nowgive a detailed description.

A, figs. 1, 2, and 3, represents the rotating cylinder of an ordinary.lniitting-machine, in which is now made a cam-groove, B K, in the usualmanner; and

B represents the inner or stationary cylinder, in which are nowc-ut thevertical grooves O, O, &c., for supporting and guidingthe needles D.

But, as both of these parts are now in use, no claim of novelty is madeto them, or to the functions which they now perform.

In the inner periphery of the cylinder A, and extending from its lowerend to the cam-groove B, is made a vertical groove, S, which has a depthcorresponding to the depth of the ordinary needle-groove .l, which isused to put the needle in the machine.

This groove S permits the needle to drop down below the top of thecylinder B, and the lugs V on their lower ends to rest in a recess, 1fig. 2, at the bottom of said cylinder.

A flange, G, projecting upward from the bed-plate ll of the machine,holds thc needles to or near the back of the grooves (l.

1 represents a spring, which is rigidly attached to the rotatingcylinder A, and has a stop, I), projecting inwardly and through saidcylinder, the latter having a suitable hole through it for this purpose.This stop so closes the upper end of the groove S as to make thecam-groove K B continuous when the machine is in ope ation; but it canbe so drawn out, shown at fig. 2, as to permit the needle .to rest inthe groove 1 as shown at fig. 3.

The operation is very simple, requiring only that the groove J' bebroughtopposite to any one of the grooves O, and the spring I drawn outfar enough to permit the needles to pass down, as shown at fig. 3.

To those skilled in this particular art no furtherdescription isnecessary.

Having thus described our invention,

\Vhat we claim as new, and desire to secure by Lettors latcnt of theUnited States. is 4 The combination of the cylinders A B, bed-plate H,grooves F S, andstop device I b, all constructed andoperatingsubstantialiy as [and for the purpose set forth.
